Hull care you can actually see
Our underwater drone brushes your hull right at your slip. Its camera records the whole visit, so you see the bottom of your boat without hauling out or taking anyone's word for it.
- Video of your hull after every visit
- A fixed day on your calendar, Monday to Friday
- Growth collected in a filter bag, not left in the water
- Brushes matched to your hull, so antifouling paint isn't scraped
What grows below your waterline
Move across the hull, or drag the bar, to compare a fouled bottom with one kept on schedule. Drag the boat to turn it.
